Crumble up some newspaper into balls and tape to the ends of a big cardboard tube.

Make a simple, thin glue from flour and water (boiling gives it a nice consistency). Mix 1 cup of flour into 1 cup of water until the mixture is thin and runny. Stir into 4 cups of boiling water. Simmer for about 3 minutes, then cool. (You can make this glue without cooking it, but it isn't as smooth that way.) Have an adult do the cooking.

Have children tear a lot of strips of newspaper and/or brown bag paper. Strips should be about 1 inch wide; the length doesn't really matter.

Dip a newspaper strip into the cooled glue, then wrap it around the dinosaur bone. Cover the entire bone, then let it dry (it make take a day or more to dry).
